Help with an error code

[kevincro]

I get the following error which points to the following line of code.  Any ideas?

 

Warning: preg_replace() [function.preg-replace]: Compilation failed: reference to non-existent subpattern at offset 5 in public_html/view.php on line 61

 

foreach($card as $key=>$cards) $hand = preg_replace($key, $smiley_img, $hand);

Does your $key variable have the forward slashes?

 

$card = array(

"/example/" => "bleh",

"/pizza/" => "test"

);
